Public bug reported:
On my desktop when I set "System settings > Power > Suspend when
inactive for" to any time (5 minutes, say), and wait, Ubuntu suspends.
When I power my desktop back on, it boots without the usual chatter on
the screen and the screen stays entirely blank (the monitor is in power-
save mode). At that point the only workaround is to force a reboot by
holding down the power button for 4 seconds, and go through the ordinary
boot process.
This appears to be the same symptoms as Bug#1283938, the last comment of
which says "file a bug by running 'ubuntu-bug linux'", which is what
I've done here. I have had the problem for years but have not reported
it until today.
My desktop has an Asus M4N78 Pro motherboard, which uses an NVIDIA
GeForce 8300 chipset. lspci reports the graphics controller as "NVIDIA
Corporation C77 [GeForce 8300] (rev a2)". "Software & Updates" says I am
using "NVIDIA legacy binary driver - version 304.135 from nvidia-304
(proprietary)". As discussed in Bug#1639180 comment#65, I cannot use the
latest NVIDIA driver as it has so many artifacts on the screen that it
is unusable.
